Damaged RF Feed or Ground Pins
The main antenna and the GPS antenna have pins (spring clips) that should properly
touch the PWB. If the RF feed pin of the main antenna does not touch the PWB, the
antenna gain will degrade by more than 25 dB and the GPS antenna will be detuned. If
the ground pin of the main antenna does not touch the PWB, the antenna gain may
degrade about 5 to 10 dB and the GPS antenna will be detuned.
If the RF feed pin of the GPS antenna does not touch the PWB, then the GPS antenna
gain will degrade by more than 20 dB. If the ground pin of the GPS antenna does not
touch the PWB, the GPS antenna gain may degrade more than 5 dB.
Figure 5: Back view of the internal antenna
• If either the RF feed pin or ground pin are broken or bent such that either pin will
not touch the PWB, then replace the internal antenna.
• If the springs for the RF or ground pin appear damaged, then replace the internal
antenna.
Damaged IHF Speaker Pogo Pins
In Figure 5, the two pogo pins on the back of the internal antenna should properly touch
the PWB. If not, the PCS gain of the internal antenna could degrade about 2 dB and
there will be no audio from the speaker.
Wrong Internal Antenna Installed
The internal antenna is mechanically similar to the internal antenna for the 2285, 2270,
2275 (RH-3 series) and the 2280 (RH-17) phones. There are three important differences
between the internal antennas:
• Only the internal antenna for the 6015/6015i/6016i/6019i, and 6012 phones
includes an IHF speaker.
• The slot pattern is very different among all three antennas.
• The radiators for the 2285, 2270, 2275 (RH-3 series) and the 2280 (RH-17)
phones are marked with an “F” and an “H” respectively.
